M92 (NGC 6341), globular cluster type IV, in Hercules. Taken May 16, 2008 with a DSI Pro II and
Outback Cooler, on a C8NGT (8" Newtonian f5) and an ASGT mount. RGB subframes were 1 minute
resulting in the following total exposures R:G:B (min) = 56:57:56 (min). Color balance was achieved
via numerically scaled channels. The RGB channels were also used to create a synthetic Luminosity
channel for processing. Captured with Envisage, calibrated and sigma combined in Iris with other
processing using FITZ, PixInsight LE and Photoshop CS. North is up.
